I would ask you when did you have your plugs changed? I am guessing you are not hitting your timing targets which is the primary way a tune increases power. WIthout good plugs you will knock before ever hitting the targets
It also losses rpm and bogs while ideling somtimes, that's rare tho!! Ill change them and Re'dyno
